Thank you for sharing this! Currently the plugin is designed to auto-send push from a post publish, but this is a good use case we will consider as well!
You should be able to add the custom post type to the plugin: https://documentation.onesignal.com/docs/web-push-wordpress-faq#for-posts-created-from-3rd-party-plugins
Or using our API directly, some details on hooking into the plugin here: https://documentation.onesignal.com/docs/web-push-wordpress-faq#customizing-wordpress-plugin-behavior
Unfortunately depending on the plugin’s custom setup, it may require adding the code through the 2nd link to hook into the event. The onesignal_include_post & onesignal_exclude_post should help do this.
If you have any further questions, for faster support, please reach out to our support team at [email protected] or through the intercom link in the bottom right corner of our documentation or onesignal.com dashboard. Happy to help!
